Hard news to read. Jim was someone trying to give back to our hobby and, if possible, eek out a modest income from the effort. I always thought he did a great job of conveying practical information when other people were drilling into mind numbing minutiae.
Jim had a sense of humor in the early days of the OGR forum and he and I used to trade notes occasionally. One of the highest compliments I ever got on the forum was a note from Jim after a sanctimonious dundermuffin raised heck over one of my O-Gauge Confessional threads. Jim told me the complainer was a stuffed shirt who needed to lighten up and to keep posting the Confessional because he always enjoyed the predicaments members were always putting themselves in. I always took that to heart.
I also used to enjoy trading notes with him about his time at Kenner. Good stuff.
Take care Jim.
